DIMENSIONS: • Dimensions of size • Dimensions of position
GEOMETRIC DIMENSIONING AND TOLERANCING (GD&T) • Uses symbols to specify geometric characteristics and dimensional requirements • Current GD&T standard: ANSI/ASME Y14.5M-1994 • Symbols for: • Form and profile tolerances • Orientation tolerances • Location tolerances • Runout tolerances
GEOMETRIC DIMENSIONING AND TOLERANCING (GD&T) • Feature control frame
GEOMETRIC DIMENSIONING AND TOLERANCING (GD&T) • MMC – Maximum Material Condition • LMC – Least Material Condition • ISO standard of preferred metric limits and fits: In the dimension 16h11, the tolerance zone is specified by a letter and a number, I.e. h11. An uppercase letter indicates that the tolerance applies to the hole; a lowercase letter indicates the tolerance applies to the shaft.
